- While this topic that I'm about to bring up isn't Scuba in the normal sense
- of Scuba diving that most of us do, this does seem to be the most
- apporpriate board for this.
-
- In a recent issue of Outside magazine, they did this article about a guy
- who wanted to do some diving in the world's deepest cave system. His
- problem was that all existing scuba technology did not allow him enough
- downtime in the water. So, he scrounged up a few million dollars, did lots
- of reading, designed and built a complete closed, rebreathing system.
- Because this was potentially BIG money yet to be patented, the article
- writer had sign a confidentiality form indicating that he would not write
- about the technical aspects of the system.
-
- My question: has there been any more information? Does anyone have any idea
- how a system such as thus might work?
-
- This guy does have a several working models; it's probably well beyond beta
- testing. The pictures of it look pretty high-techy. The inventor said that
- the whole thing has redundant designs in it for safety and is driven by
- several computers. From what I remember, the system takes a diver's
- exhalation, remove the CO2, and recycles the rest back into the system
- again. I think he calculated his system to be able to support dives
- measured in the teens of hours (13, or 16).
-
- NASA and US Navy apparently very interested.
